Abstract:
We designed a retrospective study to analyze suicidal drowning deaths occurring between 1981 and 2005. During the study period there were 134 cases of suicidal drowning accounting 10% of all suicides, and 31% of all drowning deaths. Of the 134 drowning suicides, 76 (57%) incidents occurred in the sea, 46 (34%) in water wells, 8 (6%) in rivers, and 4 (3%) in bathtubs. During the study period, cases of suicidal drowning were not identified in males and females under the age of 20. In females aged 65 years and older, drowning represents the most common type of suicide. Commonly, the victims were sober at the time of the incident. Cases of suicidal drowning committed in water wells are unexpectedly high, considering abundance of salt water.

Titration Calculations: Strong Acid - Strong Base
A titration is carried out for 25.00 mL of 0.100 M HCl (strong acid) with 0.100 M of a strong base NaOH. The pH at different volumes of added base solution can be calculated as follows:
(a) Titrant volume = 0 mL. The solution pH is due to the acid ionization of HCl. Because this is a strong acid, the ionization is complete and the hydronium ion molarity is 0.100 M. The pH of the solution is then:
